| Title: | System Size, Lock-in and Network Effects for Patient Records |

| Abstract: | We examine empirically whether the size of a firm using a network
affects the scope of its network usage, and consequently network effects
and lock-in within the network. We use the example of hospital
information exchange. We find that hospitals in larger hospital systems
are more likely to exchange electronic patient information only within
their system and less likely to exchange patient information externally.
We show that hospitals are also more likely to exchange information
externally if others hospitals also do so. This implies that the
disinclination of large hospital systems to exchange data externally
harms overall levels of network use. Our results highlight that makers
of technology policy designed to encourage the optimal use of networks
should consider regulating the behavior of network users as well as
technology vendors. |
